• Why UTF-32 instead of UTF-16 if we have surrogate pairs?

  - by zildjohn01

  If I understand correctly, UTF-32 can handle every character in the universe. So can UTF-16, through the use of surrogate pairs. So is there any good reason to use UTF-32 instead of UTF-16?

• [PHP] Read and write to a file while keeping lock

  - by Znarkus

  Hi! I am making a simple page load counter by storing the current count in a file. This is how I want to do this: Lock the file Read the current count Increment it Write new count Unlock file/close it Can this be done? As I understand it, the file can't be written to without losing the lock. The only way I have come up with to tackle this, is to write a character using "r+" mode, and then counting characters.

• vim unicode bufread/bufwrite script

  - by anon

  Problem: I want my unicode characters to be stored on disk as (rather tan utf8/16 encoding) \u#### However, I want them dispalyed as unicode characters when opened up in vim. I think the easiest way to acheive this is some bufopen/bufwrite script that automatically: on opening, convert \u#### to unicode character on writing, convert unicode characters into \u#### However, I don't know what functions to call to make this happen. Can someone lend a hand? Thanks!

• How to encrypt/decrypt a long string in PHP?

  - by jodeci

  I doubt if this is encryption but I can't find a better phrase. I need to pass a long query string like this: http://test.com/test.php?key=[some_very_loooooooooooooooooooooooong_query_string] The query string contains NO sensitive information so I'm not really concerned about security in this case. It's just...well, too long and ugly. Is there a library function that can let me encode/encrypt/compress the query string into something similar to the result of a md5() (similar as in, always a 32 character string), but decode/decrypt/decompress-able?

• How to generate a transaction number?

  - by 001

  I was thinking of formatting it like this TYYYYMMDDNNNNNNNNNNX (1 character + 19 digits) Where T is type YYYY is year MM is month DD is day N is sequencial number X is check digit The problem is, how do I generate the sequencial number? since my primary key is not an auto increment integer value, if it was i would use that, but its not. EDIT can I have the sequencial number resets itself after 1 day (24hours). P201012080000000001X <-- first transaction of 2010/12/08 P2010120810000000002X <--- second transaction of 2010/12/08 P201012090000000001X <--- First transaction of 2010/12/09 (X is the check digit)

• Scala println in a for loop

  - by random459

  The following Scala code does just what I expect it to - it prints each line of some_file.txt. import scala.io.Source val lines = Source.fromPath("some_file.txt").mkString for (line <- lines) print(line) If I use println instead of print, I expect to see some_file.txt printed out with double-spacing. Instead, the program prints a newline after every character of some_file.txt. Could someone explain this to me? I'm using Scala 2.8.0 Beta 1.
